This improved hay stackeror derrick is so constructedthat itmaybe used for lifting'hayffroma wagon and depositing the hay upon a stack but is lintended for general w ere heavy loads are' to b'e'lifted land transported from-:one position to another. may be used Aas "a portable device or it could'be `built upon a `stationary platform and. usedfor unloading carsat-a railway station or'at any other suitable` place; In thefpresentillustration, the' device is shown aspportable a-ndis. provided with. a base which is triangular ,in shape and provided which' arev braced by? cross forwardl end portion of" the base and pro'- through` the base and carries aftiller or turnso that the truck may be turned inorder to guide-the device when it is being moved from i one/place .to another. This truck is provided with. an aXleQG which carries wheels 7.

neath the-rear ends of 'the side beams land with these .hangers 8;-soy that the rear portion of thebasewill zbe supported and easy movementof the" hay stacker permitted. l A tonguel() extends from the forward endof is provided at its free end with a.-elevis .11 through which a stake 12 ma beV .driven in A tongue10 is .removably the device is being moved from one place to anotherby draft animals. Of course, it'isunders'tood that if awtractor is usedefor drawinglthe stacker from one place -to another,` a lconnecting chain leading from the tractor `would besecured inthe elevis.' r i IThe mast 13 has its lower end resting in a socket-plate'lf sothat'the mast mayrotate andthe upperportion.y of the mast'extends through acollarlfwhieh is carried' by bars' c-E I f perspective view of therlatch HangersS are positioned ybe- 4 which extends upwardly order Ato anchor Vthe vstacker 16,'v These vbars 1.6l are'carried by the sidel beams land are;y braced by the bracinw-strips 17. G uywires18 .are connected -wlth the i cai-ry pegs`19 whiclif will be drivenrinto the supporting bars 16 and these guy wires 18 p between the side'bars 36 o vwhich includeemeans for rotatably ymountbolt 27 carries -ap11lley 'end portions of the .bolt

ground to hold the; hay stacker stationary. This mast has its upper end provided with a transversely extending lopening throughY which extends a pivot sha-ft 20, the Vpivot shaft being braced bythe supporting strips 21 whiehare secured to the mast by fasteners 22. 'Al bar o r arm 23extends radially from the lower end port-ion of the mast and has its free end portieri provi djedgwith trans-v versely extending opening for receiving a re` movable fastening 'pin/24. vSlt will thus 4be seen that ythere Vhas-been provided va'base ing thepmast, thejcollar l and supporting bars 16 serving to brace the mast and. retain it in a verticalposition.v l. p The crane isfprovided withsidel bars 25` which arerloosely mounted upon.thepivot shaft 2()and Vhave their innerend portions.. connecte'dby the yoke 26 and their outer end portions connected by bolts 27 and 28. The .housing 29 having the usual pulley wheels'BO andthe `cable .or rope 3l will be connected with vthe bolt-"28 between the sidey bars 25and .willvtllien'ber` passed through he pulley wheels 32 `which carry the load engaging hook 33.v The rope will then ybe passedy around the vpulley wheel 3 0 and extended inwardly fover a pulley wheel 3,4 which is mounted in .a pulley hous-A ing 35. This pulley'housin 35 is supported a vertieallyzextending brace by means of a pole4 37. IThe side bars of thisbrace -are looselymounted upon the pivot shaft` and secured to the side bars of the crane by rivets 38 yas shown in Fig.'r4. The upper ends of these side bars 'ofthe brace are connected'by` a bolt -39 and this bolt 39 is engaged `by a lbracing rod: 40 the vouter end of which is connected with the bolt 28. This bolty 39 also kserves as securing,r meansl for themounting 41g which carries the pulley wheel .42. Guy wires 43 are .connected with the outer 39 :and with the pivot rod 20 and serve to holdthe .brace formed by the Vbarst so that this bracewill be prevented from having transverse movement which would tend to work it loose or break it.'` Inaddition to carryingk the crane and brace Vforthe crane,V the. pivot bar 20 carries an arm which is composed. of side bars 44 mounted upon the pivot bar and having their opposite` endportions connected by a bolt .44v upon which wi1l-be positioned a spacing sleeve 45. .The freeendportions of these side bars 44 are provided with open ings for'vreceiving the ypin 24` will .thus be seen; that the armormed by these side bars'may be ,releasablyfconnected with the arm 23. This arm l'which may be termed ya counter-balancing arm tor the crane vrhas its side .barsl provided with `bea-ring 'plates .46 which A.form bearings for drum 47,'the yshaft of: which carries .a turningv wheel4S. This 'shown inv fulllines in positioned at the the hook 33 and .at the Asame time;

turningwheel orfdisk 48 carries ratehet'teeth 49f`engaged by a oawl 50 so that when'the drum is rotated to wind the cable 51 uponl the -dru1n, the dru-m VVmay Y be held against rotation tounwind thecable: vThis cable l5l has one Vend connected Y` with medley. and'rconnected with the ySleeve 45 mounted upon the bolt 44. Therefore, when the cable is wound upon lthe -drum,the crane willbe; swung upwardl indicated-by VAdotted lines in sthis figure. ft will thus be seen, that the .cra-ne may be 52 is ymounted upon the larme23 andtheeable 3ll is passed about and `is then carried outwardlysort at itfrnay be connectedwith a draft appliance'. Therefore,a team ,of draft animals may draw'fthe line to 'lift the load which fis' .engaged-.by

thelorane may be'swung upwardly if necessary. After the load .has been :drawn toy theraised position, the mast and crane-may be 'turned to swing the-crane to 'a positionabove the hay stack and the load will be released. 1n order` to release the load, the linegwhich is connected with the releasingline 5.4'will be drawnupon and the line 541wil1be .moved torelease the hook and lper-mit the load ot hay to drop upon theV stack, lIn -orc le1 @to prevent the mast from turningl and permitting the kcrane-to `,swing.-,while'the load sbing drawn upWerd1y,-.therehas :been pre vided a latch 55 Vwhichfis pivOielllyconneeted with one of the supporting .bars land when in an operative position will Vrestlupon the arm 234, Thereforefthe 'hooked .end portions V56 ofthe ylatch will-prevent .thearm 23 lQlfn when the Aerm engages the curved enel-portions of the camelement, the latch will be 'moved upwardly and :the latch will ride-.over the arm 23- thus permitting' Vtheelffule' "toghe .can then be released .wl-ien"v the crane .s returned tothe position above the'wagon,

It will :I thus ibe- `:from the position ig. l towardsgthat seen that the team .of dnaftanirnals agiter drawing '.thecable y31V to raise-gthle' dead, may

, necessary tov pass beneath telephone wires or some vother similar obstruction, and the crane is in the elevated position indicated Vin dotted lines in Fig. l, the pin 24 can be withdrawn and the ciane tlien swung downwardly a vsuiicient distance to pass beneath the wire with the bracing bars 44 swinging upwardly. It is, therefore, not necessary to release the cable 51 and swing the crane downwardly. This saves time and labor on the part of the operator of the derrick. After the obstruction'has been passed, the bai' 44 will be drawn downwardly to return the crane to the original position and thel securing pin replaced. As previously explained, vthis device may be built Vupon a stationary platformif so desired instead of employing the carriage which includes the side beams 1, `cross bars 2 and supporting truck.
